Low Voltage 8-Bit Constant Current Led Sink With Full Outputs Error Detection

Low voltage 8-Bit constant current LED sink with full outputs error detection The STP08DP05 is a monolithic, low voltage, low current power 8-bit Shift register designed for LED panel Displays The STP08DP05 contains a 8-bit serial-in, parallel-out Shift register that feeds a 8- bitD-type storage Register In the output stage, eight regulated current sources were designed to provide 5-100mA constant current to drive the LEDs The STP08DP05 is backward compatible in the functionality and footprint with STP8C/L596 and extends its functionality with open and short detection on the outputs. The detection circuit checks 3 different conditions that CAN occur on the output line: short to GND, short to V or open line. O The data detection results are loaded in the shift Register and shifted out via the serial line output. By STMicroelectronics
